Tam sim no Transformer Connections nyob rau hauv Fais Systems

(Nyem daim duab kom paub ntxiv.)

Transformers yog ib qho ntawm cov khoom hauv lub tshuab hluav taws xob uas feem ntau mus tsis tau pom dua -kom txog thaum muaj qee yam tsis raug. Lawv nyob ntsiag to tswj cov kev hloov pauv hluav taws xob kom hluav taws xob tuaj yeem txav mus ntev thiab tom qab ntawd siv nyab xeeb hauv tsev, chaw tsim khoom, thiab cov tsev. Tab sis nrog rau lawv, muaj lwm yam khoom siv ua haujlwm sib txawv uas yog qhov tseem ceeb: tam sim no transformer. Thiab ncaj ncees, ib zaug koj pib ua haujlwm nrog cov tshuab zoo li no, lub ntsiab lus ntawm kev sib txuas ntawm transformer tam sim no tuaj txog txhua lub sijhawm.

Lub Fais Fab Transformer yog tsim los hloov hluav taws xob hluav taws xob ntawm qib voltage. Nws cuam tshuam nrog lub zog tiag tiag thiab feem ntau yog ntsuas hauv kVA lossis MVA. Tab sis ntawm no yog qhov ntes tau - nws tsis yog tsim los muab cov cim kev nyab xeeb rau cov ntsuas lossis cov cuab yeej tiv thaiv. Qhov ntawd yog qhov uas tam sim no Transformer (CT) nkag mus rau hauv. Nws yuav siv sij hawm siab tam sim no thiab ntsuas nws mus rau ib yam dab tsi tswj tau, feem ntau yog 5A lossis 1A, yog li cov cuab yeej tuaj yeem nyeem nws yam tsis muaj kev puas tsuaj.

Thaum tib neeg tham txog tam sim no transformer kev twb kev txuas, lawv tau hais txog yuav ua li cas cov CTs tau xaim mus rau hauv lub cev -tshwj xeeb nyob ib ncig ntawm transformers, switchgear, thiab kev tiv thaiv panels. Thiab txoj kab no tsis yog qhov nthuav dav xwb. Nws cuam tshuam ncaj qha rau qhov system nyeem tam sim no thiab nrawm npaum li cas nws hnov ​​​​mob thaum muaj qee yam tsis raug.

Hauv kev teeb tsa tiag tiag, CTs feem ntau yog muab tso rau ntawm ob sab ntawm lub zog hloov hluav taws xob. Ua li ntawd, engineers tuaj yeem pom dab tsi los hauv thiab tawm mus. Yog tias ib yam dab tsi tsis sib xws, nws yog tus chij liab.

Ib qho tseem ceeb tshaj plaws ntawm kev siv tam sim no transformer kev twb kev txuas yog nyob rau hauv kev tiv thaiv sib txawv. Lub tswv yim yog yooj yim: nyob rau hauv ib txwm tej yam kev mob, tam sim no mus rau hauv ib tug transformer yuav tsum phim dab tsi tawm los. Yog hais tias muaj ib qho txhaum nyob rau hauv, qhov nyiaj tshuav ntawd tawg. Lub kaw lus tiv thaiv ntes nws thiab mus ncig lub voj voog yuav luag tam sim. Tsis muaj hesitation.

Kuj tseem muaj cov ntsiab lus me me tab sis tseem ceeb uas tib neeg qee zaum saib tsis dhau -polarity. Yog tias CT raug xaim mus rau txoj kev tsis raug, kev nyeem ntawv tuaj yeem tawm tag nrho lossis kev tiv thaiv kab ke yuav tsis ua haujlwm zoo. Tias yog vim li cas terminals zoo li P1, P2, S1, thiab S2 yog cim kom meej thiab yuav tsum tau ua tib zoo ua raws li. Tsis muaj shortcuts ntawm no.

Hauv kev ua haujlwm txhua hnub, kev sib txuas ntawm lub tshuab hluav taws xob tam sim no ua rau lub neej yooj yim dua. Nws cia cov kws ua haujlwm saib xyuas cov dej ntws siab nyab xeeb, yam tsis muaj kev cuam tshuam ncaj qha rau cov qib txaus ntshai. Nws kuj tseem pab nrog kev ntsuas lub zog, kev taug qab kev thauj mus los, thiab kev kuaj xyuas qhov tsis raug hauv cov chaw nres tsheb thiab cov chaw tsim khoom lag luam.

Thaum kawg ntawm lub hnub, lub zog transformers txav zog, tab sis CTs thiab lawv txoj kev sib txuas pab tau peb tiag tiagsaibthiab tswj qhov tshwm sim hauv qhov system. Yog tias tsis muaj kev sib txuas ntawm cov khoom siv tam sim no, cov khoom siv hluav taws xob niaj hnub no yuav nyuaj dua rau kev tswj hwm - thiab tsis muaj kev nyab xeeb ntau.
